Really nice work! Especially for those who really like the perfect sultry bad boy. I particularly like the profile.

I would want to masculinize him a bit --  more texture on the skin, eyebrows less manicured, stubble, less refined features, some asymmetry in the face.  

Your character would be a very good starting point for what I'd want to do to him. I'm definitely not suggesting you change that perfection you've got. Sometimes absolute perfection is what an image wants, and it's very popular in the market. Plus it's much harder to idealize a morph that has realistic flaws than to introduce those flaws into one that is perfect. So I think you should keep the morph pretty much as he is. Though some bump for skin texture would be essential, I think. Also, even if he's smoothly shaved, he needs subtle evidence of facial hair. I think this could be achieved with just very delicate shading and bump, rather than actually pasting on stubble. But I'm not sure. He's more like an idealized painting than a real human -- and there's nothing wrong with that. In fact, just judging from the galleries, I think it's what most buyers really want.

As for tattoos, I'd say, go full romantic goth -- you've got a great start with the shoulder tat. Whether you intended it or not, the guy IS a vampire.

Edit: Oh, and the idea of gothic-cyber... cool. Actually combining both concepts sounds very intriguing.
